Supra-Normal Left Ventricular Function

The American Journal of Cardiology, 2023
Heart failure (HF) is often categorized by left ventricular (LV) ejection fraction (LVEF). A new category of HF characterized by supra-normal LVEF (>65%), named HF with supra-normal ejection fraction (HFsnEF), has been recently proposed. Some studies reported that patients with supra-normal LVEF might have an increased risk of long-term major adverse ...

Left ventricular function in malnutrition

American Journal of Physiology-Heart and Circulatory Physiology, 1987
Twenty-one dogs were chronically instrumented with ultrasonic left ventricular dimension transducers and micromanometers to elucidate the effects of acute protein-calorie malnutrition on cardiac function. Ten dogs received a regular diet for 3 wk, whereas 11 dogs received a protein-calorie-deficient diet designed to achieve a mean weight loss of 20-25%

Left Ventricular Aneurysmectomy in Patients with Poor Left Ventricular Function

Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1992
Physical performance and left ventricular (LV) function in the resting state were assessed in 22 patients with postinfarction anterior-apical left ventricular aneurysm (LVA) and global ejection fraction less than or equal to 20% who subsequently underwent radical LVA resection.

MRI of left ventricular function

Journal of Nuclear Cardiology, 2007
Cardiac magnetic resonance imaging (CMR) is widely recognized as the most accurate noninvasive imaging modality for the assessment of left ventricular (LV) function. By use of state-of-the-art magnetic resonance imaging (MRI) scanners, electrocardiography (ECG)-gated cine images depicting LV function with high contrast and excellent spatial and ...

Assessment of Left-Ventricular Function

The Thoracic and Cardiovascular Surgeon, 1998
There are three distinct phases of the cardiac cycle (contraction, active relaxation, and passive relaxation) which should be examined in order to perform a thorough assessment of global left-ventricular function. Accurate measurements of left-ventricular pressure and volume are necessary to assess these phases of the cardiac cycle.

Left ventricular diastolic function

Critical Care Medicine, 2007
Cardiovascular morbidity and mortality resulting from congestive heart failure are major concerns for the critical care physician. Although heart failure is commonly associated with impaired systolic function, in up to one half of cases, heart failure occurs exclusively on the basis of an impairment of diastolic function.

Left Ventricular Function

Giornale italiano di cardiologia, 1994
TEE is widely used for intraoperative monitoring of global and regional left ventricular function during cardiac surgery. However, caution is necessary in assessing changes in left ventricular function before and after cardiopulmonary bypass because of the unequal loading conditions and the interference of catecholamine administration.

Left Ventricular Function in Patients with Centrifugal Left Ventricular Assist Device

ASAIO Transactions, 1989
We used blood pool radionuclide angiography to study the left ventricular (LV) ejection fraction (EF) in 17 patients with a centrifugal assist device (AD) placed because of severe postoperative LV dysfunction. During maximal LVAD flow, the 12 patients who could be weaned had a higher LV-EF than the 5 who could not be weaned (18 +/- 12% vs. 9 +/- 2%, p =

Estimation of Left Ventricular Function in Patients With a Left Ventricular Assist Device

ASAIO Journal, 1995
Patients with profound left ventricular (LV) dysfunction supported by a left ventricular assist device (LVAD) may have recovery of LV function, but current methods for assessing this are difficult or not readily available. A new method to estimate LV performance was tested in 6 patients on LVAD (age, 47 +/- 12 years).
